STRAW-STACK'ER.

SPECIFICATION forming part of iLetters Patent No. 277,720, dated May-?, 1883.

Application filed March 12, 1883.

To all whom it may concern:

Be it known that I,-FERDNAND F. HART- WIoH, a citizen ofthe United States, residing at Onaga, in the county et' Pottawatomie and State of Kansas, have invented a new and use ful Straw-Stacker, ot' which the following is a specification, reference being had tothe accent panying drawings.V

This in' ven tion relates to straw-stackers for thrashing-machines; and it has for its objects, first, to provide means for tightening or slacking the'belts while the machine is runningwithout stopping the same; second, to provide means which enable the stacker to be folded when the machine is to be moved without first detaching the belts or apron.

My invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure l is a side view of my improved straw-sta cker. Fig. 2 is ay bottom view of the same, and Fig. 3 is a longitudinal vertical sectional view.

The same letters refer to the same parts in all the figures.

The frameofmy improved straw-stackerconsists of the two parts or sections A and B, which are connected by hinges C, so as to be capable of being folded in the usual manner. The lower section, A, may be hinged upon the shaft of the thrashing-machine, which carries the lower band-wheels,npon which the apron or the belts D ot' the same are arranged to run. The upper band-wheels, E E, are mounted upon a shaft, F, the ends of which are jonrnaled in boxes G at the upper ends of a pair of rods or "straps, II, which arel Iitted to slide in stirrups or brackets I upon the under sides of the side pieces J of the upper section, B, of the stackerlrame. The lower ends of the straps H are bent inward and hinged by a transverse pin to a bar, K, sliding in stirrnps or hangers L, centrally under thelowersection, A, ofthe stackeri'rarne. The side pieces M M of the said lower section have bearings for a transverse shaft, N, carrying a pinion, O, engaging slots or openings P in the bar K. The end of shaft N has an operati n g-crank, (2 and it carries a ratchet.-

(No modeLi upon the stacker-frame, thus loosening or tight,`

ening the belts, as may be required, and this may be conveniently done at any time d nring the operation of the machine. The parts H H and K being hinged together, as shown, will not interfere with the folding of the stackert'rame. r

T is a rod swiveled to one side ot' the stacker-frame, just below the hinge, and having at its free end a hook, U, which may engage a catch, V, at the opposite side ot' the frame. When theframe is to be folded for tra nsportation the said rod retains the apron in its proper position, making it unnecessary to remove the said apron before folding the stacker. During the operation ot' the device the rod T is disengaged from the catch V and held by a. similar catch, W, near the lower end of the stacker frame, so as to be ont ot the way of the apron.

I claim as my invention and desire to secure by Letters Patent of the United Statesl. In astraw-stacker for thrashing-machincs, the combination, with the frame composed ol' two parts or sections, h inged together as shown, of the straps sliding' under the side pieces of the upper section, and carrying at their upper ends a shaft having the upper bandwheels, and having their lower ends bent inward, abar hin ged between the said lower ends, and meehanism for sliding the said bar upwardly and downwardly and for retaining it in anyposition to which it may be adjusted, as set forth.

2. The combination of thefolding stackerframe, consisting of the sections A B, hinged together as shown, the straps H, sliding in stirrnps I under the sides of the upper section, B, and having theirlower ends turned inward, the bar K, sliding in stirrnps L, centrally nnn der the lower section, A, and hinged between the lower ends of the stra-ps H, the shaft N, pinion O, engaging slots P in the bar K, crank Q, ratchet wheel R, and the pawl S, all arrmi ged and operating substantially as set forth. 3. In a straw-stacker for thrashing-machines, the combination, with the folding stacker- 5 frame, of the rod T, swiveled below the hinge, Witnesses:

and having zt hook at its free end, and the FRANK B. LANDON, catches V W, as and for the purpose set forth. l M. F. HARTWICH.

In testimony that I claim the foregoing as my own 1 have hereto affixed my signature in presence of' two witnesses.
